Abstract
The utility model discloses a gearbox comprising a drive shaft serving as a power source, a transmission main shaft, a transmission auxiliary shaft, a speed-changing drum, a shifting fork, and a shifting fork shaft, wherein the transmission main shaft and the transmission auxiliary shaft have speed changing functions, a driving gear is arranged on the drive shaft, the driving gear is meshed with a driven gear on the transmission main shaft to form the power source, and the transmission main shaft further comprises a first gear, a second gear, a third gear, a fourth gear and a fifth gear. The first gear, the second gear, the third gear, the fourth gear and the fifth gear are respectively meshed with corresponding gears on the transmission auxiliary shaft. The fourth gear of the transmission main shaft, and a third gear and a fifth gear of the transmission auxiliary shaft are shifting gears and are matched with the shifting fork to be used. The shifting fork is arranged on the shifting fork shaft, a protruding circular shaft on the shifting fork is installed in the speed-changing drum, and the speed-changing drum enables the shifting fork to rotate and move left and right to achieve the shifting function. The gearbox has the advantages of being fast in shifting, light, stable, whomp-free, good in sealing, good in lubrication, long in service life, and compact in structure.
